Yeah, but that's €1.65 from €1.20 in the not-too-distant past.
I've seen greeting cards for as much as €7/€8, rather extravagant for a child. The card itself was from Mr Price as I recall, purchased in desperation as it just said "Congratulations" on the front with no qualification regarding the occasion - no baby, job, engagement, or divorce printed and no message inside, just a blank page, ideal for personalisation.
I have a couple of little label printers that can do fancy insides for blank cards and a range of type-faces to jazz them up. €1.99 for the card I think, and about €30 for the BlueTooth printer from Amazon, Nelko PM220. I needed one as holding a pen and writing are both difficult these days. Take the little printer and my phone to the Post Office and the job is Oxo, address and greeting legible for all.
